| Work Hardening for Extreme Impact and Abrasion |
| A basic coated electrode depositing an austenitic
manganese steel weld metal. The deposit is highly
resistant to heavy impact and abrasion. The deposit is
work hardenable. The electrode is recommended for
surfacing of worn-out austenitic manganese steel parts.
It can also be used to give impact protection on carbon
steels. |
| |
| ALLOY BASE |
| Fe, Mn, Ni, Cr |
| |
| SPECIAL FEATURES |
- Build-up is free from cracks (with proper welding
procedure)
- Superior arc stability than available grades of Mn
Steel electrodes
- It is very easy to use in all positions
|
| APPLICATIONS |
| Austenitic manganese steel components, crusher jaws,
crusher hammers, crusher mantles, dredger bucket
teeth, cement grinder rings, manganese steel railway
points & crossings, manganese steel components used
in the mining industry. |

| WELDING PROCEDURE |
- The surface to be welded should be without prior
work hardening
- 14% Mn steel should never be preheated for
welding
- Welding should be done in stringer beads directing
the arc towards the weld pool keeping the heat input
to the base metal minimum. Skip welding / back step
welding can also be adopted
- The weld bead can be peened with ball pen hammer
immediately after welding
- Quenching has no adverse effect on welding and
should be adopted whenever possible after slag
removal and peening. If possible the Mn steel job
can be submerged in water during welding
